The campuses slow down event-wise when the students are out of town:
But, the museums are open:
Harvard Museum of Natural History
The latter is only one of nine listed science museums at Harvard.
These include the Arnold Arboretum, also quiet this time of year. However, the “living collections” database, with information on the nursery’s 181 different types of lilacs, is always in bloom.
Harvard’s Collection of Historical Scientific Instruments, also offers a database of its collection, with includes microscopes, globes, Judah Folkman’s telescopic surgical spectacles as well as tools and lenses from Edwin Land, inventor of the Polaroid camera. If you want to see a saccharimeter, a reflecting galvanometer, an ophthalmotrope or an alternating ammeter, this is the place togo.
On display, an exhibit called Time, Life and Matter
Highlights of the exhibit include a multitude of stories told in part by such items as a
geometric sector designed by Galileo, electrical experimentation apparatus purchased on Harvard’s behalf by Benjamin Franklin, a suite of clocks illustrating the development of modern synchronized time-keeping, medical apparatus designed, in part, by Charles Lindbergh (yes, that Charles Lindbergh), and the artifacts of top-secret research conducted during World War II.
